When I was a young pup, I was interested in mathematically-derived Op Art things like Moiré patterns. In 1980, the TRS-80 was quite the toy, but the limited pixel resolution (128 x 48!!) stopped you from doing too much. Still, I tried a few simple things, polar coordinate graphs and so on. If anything was too complex, it just devolved into an almost random pile of pixels, so for a little bit of time I played with the Moiré patterns you could create. After a couple of years a dot-matrix printer came on the scene and I soon was spending time waiting for the pins to punch out nifty patterns.

I've edited your formula a bit to allow for some changing parameters, which allows me to create an animation out of it (animation without changing parameters isn't as interesting, I fear).

Implement a nifty Lissajous curve with the parameters (vary them according to sine curves) and you have a set of points that alters almost forever. The four parameter components follow periods of 3, 5, 7 and 11, and I have also animated the zoom parameter to decrease about 30% from the maximum to the minimum. Might as well do that according to a prime number too, so that follows a period of 2. If you were to animate this long enough for the periods to all line up again as they were at the start, it would take just short of 80 hours. OK, this animation isn't nearly interesting enough for that, but here's a minute of it.
